I can't wait for the DS version
I'm expecting there will be all the stuff from the xbox arcade with hopefully some extra.
The multiplayer has to return of course .
Something i would really like is a mode in which you have to defend all sides off you're house at the same time with little screens appearing to show you what happens on the other sides.
I think that would be very interesting.
Maybe a little storyline or atleast give a reason why you only meat dave and all other neighbours seem to be dead already.

But yeah , popcab is awesome so they will figure it out
